Passport here as well easily 14+ hours. There are series of days that I don't even charge my blackberry. I suspect that since BlackBerry Limited does not have the cash to pay for this kind of marketing, they do not get on the list.

Oh and the amazon pricing values are wrong. The galaxy 6 egde that they link to is the 128gb version that costs ~$1k. Whereas the advertising lists 299. The low end version on amazon still costs 500+ assuming you get the proper version for your region.

This isn't really a meaningful comparison. People don't buy phones just based on battery life. It has to be weighed in with screen size, screen resolution, processor cores, processor speed, and weight of the phone.

For screen size and resolution, and for processor cores and speed, more is better. But for the battery, more capacity also means more wight. And for weight, less is better. This causes battery life to be a trade off between capacity and weight.

Phones with similar screen and processor specs are going to have similar battery drain (all else being equal.)
Balancing battery capacity and battery weight is the same problem for all manufacturer's offering those specs.

To fairly compare phones with different specs, all these specs have to be scored and weighed and a composite score calculated. Otherwise, low performing phone specs have an unfair advantage over high performing phones.

Blu studio energy 2 has 5000 mah battery, out last any of the phone listed. Also other brand such as Lenovo, Asus...etc all have huge battery phones.
Agree, people make decision base on a wide range of qualities, such as spec, weight, build quality and so forth. The title of this article is best battery phone, not best overall phone. The scope of this article should focus mainly on the battery life and size. This article is heavily biased towards the major brands, as many mid range to low end phone with amazing battery capacity were not listed. I guess the reviewer either did not do her research or gets paid by those brands.

Low quality and biased review like this make the site lose credential, I used to come visit toms website, nowadays I go to other more reliable and structured site such as linus, notebookcheck, anandtech and gsmarena. Quality research and review bring you audience.
